I have received an admission offer* from a US University for PhD program with full tuition waiver plus a TA offer. The deadline of accepting the offer is April 15. Graduate coordinator wrote me that
Please do not hesitate to contact me if you have any questions or concerns. We are looking forward to your response.
I have applied few other universities too and have not received their decisions. How to write the coordinator in a best way that, I'm very much interested but I would like to notify them (acceptance or declining) regarding admission offer around the middle of March? Will they take my view in a negative way?
*The official certificate of admission will come from the university, after all official transcripts and other necessary documents and test scores are received; until then, this offer is considered unofficial. You will be contacted by the university with a request for documents and for other details, but in the meantime here are the specifics of this offer. Students who are offered a graduate assistantship are required to accept or decline by April 15, 2016. This common deadline is based on an agreement of all institutions that are members of the Council of Graduate Schools, as described in the April 15 Resolution, a copy of which can be obtained from http://www.cgsnet.org/april-15-resolution.
